Andreas,
look at the javadoc of PDXObjectImage:
http://www.pdfbox.org/javadoc/org/pdfbox/pdmodel/graphics/xobject/PDXObjectImage.html
There you will find some methodes to work with the embedded pictures.
Have a closer look at:
getColorSpace()
If this does not fit your needs, you will have to extract the image from
the PDF and use normal graphic-libraries on the image to find out what
you need.
Greetings,
Erik

Hello,
How can I find out if an image is black and white (no greyscale, no colors)?
